Shadowcats

Shadowcats are dominant predators found in the Mountains of the Moon surrounding the Vale. They are also found north of The Wall, and while not as fearsome as direwolves, can detect blood up to six miles away and are extremly fierce. They eat all parts of the body, bones and all. After the battle with the mountain clans and Catelyn Stark's party, shadowcats are presumed to have completely disposed of the bodies.
